What is a fluorescent lamp holder
A fluorescent lamp holder is a device that is used to support and connect a fluorescent lamp to an electrical circuit. Fluorescent lamp holders are typically made of plastic or metal and consist of a socket that holds the lamp in place and a set of wires that connect the lamp to the light ballast.
Fluorescent lamp holders are available in a variety of shapes and sizes to accommodate different types of fluorescent lamps, including T5, T8, and T12 lamps. The size and shape of the lamp holder must match the size and shape of the lamp to ensure safe and reliable operation.
Differences between T8 and T5 lamp holders
One of the most obvious differences between T8 and T5 fluorescent lamp holders is their size. T8 lamps have a diameter of 1 inch (25mm), while T5 lamps have a diameter of 5/8 inch (16mm). This size difference may not seem significant, but it can affect the way the lamps fit into different fixtures.
T8 lamp holders may be too big for some fixtures designed for T5 lamps, and vice versa. It’s important to choose the right lamp holder size to ensure proper fit and function.
2. Energy efficiency:
Another difference between T8 and T5 fluorescent lamp holders is their energy efficiency. T5 lamps are generally more energy-efficient than T8 lamps.
This is because T5 lamps have a higher light output per watt, which means they can produce the same amount of light as a T8 lamp using less power. For example, a 4-foot T8 lamp typically uses 32 watts and produces 2,600 lumens of light, while a 4-foot T5 lamp uses 28 watts and produces 2,800 lumens of light.
This difference in energy efficiency may not be significant for small-scale lighting applications, but for larger commercial and industrial lighting installations, it can result in significant energy savings over time.
Can you use a T8 lamp in a T5 fixture?
No, you cannot use a T8 lamp in a T5 fixture without replacing the fixture or making significant modifications.
Differences in pin spacing and length: T8 and T5 lamps have different pin spacings and lengths, which means they are not interchangeable.
T8 lamps have a pin spacing of 1 inch (25mm) and a pin length of 23/32 inch (18mm), while T5 lamps have a pin spacing of 5/8 inch (16mm) and a pin length of 11/16 inch (17mm).
This means that a T8 lamp will not fit properly into a T5 fixture, and vice versa.
